Apr 01 03:01:33 They should fix that quirk. Apr 01 03:03:19 Or make a better screen, one w/ D&D Dragons on it or something. Apr 01 03:04:13 On Ubuntu or Debian use this Apr 01 03:04:17 https://pastebin.com/dEckY1Rb Apr 01 03:07:41 You can exit x by clicking x in upper right cornet Apr 01 03:09:41 Choose one large window and display -1 Apr 01 03:10:51 10:10! Apr 01 03:12:18 in 2020! Apr 01 03:13:20 The time is changing! Apr 01 03:20:50 Just ordered relay cape from mouser;D Apr 01 03:26:42 Nice. Apr 01 03:26:52 Now, we can participate together on the Cape. Apr 01 03:27:00 What do you plan on doing w/ it? Apr 01 03:27:37 Turn things on/off. Shpuld be here Friday Apr 01 03:27:41 Nice. Apr 01 03:27:52 Lights, Motors, Solenoids! Apr 01 03:28:07 We cab work togheter then Apr 01 03:28:32 Nice. I might get an electronic switch for a heavy door. Apr 01 03:28:44 Good thing i got that 5v supply Apr 01 03:28:59 Instead of a 2" x 4", I can use the switch! Apr 01 03:29:38 2x4 for what? Apr 01 03:29:39 Oh yea. I think these Capes from GHI only work w/ the 5v barrel jack supplies. Apr 01 03:29:43 The door! Apr 01 03:30:01 wooden beam Apr 01 03:30:10 At least, that was the case w/ the MotorCape and LoadCape. Apr 01 03:30:13 Right. Apr 01 03:30:56 well yea i expect those relaysbwhen operated draw some current Apr 01 03:31:21 KenUnix: You might want to get a barrel jack or wire one up. Apr 01 03:31:59 i got that 5v supply plugged ibto barrel jack now Apr 01 03:32:07 Oh. Okay. Apr 01 03:32:11 Nice. Apr 01 03:32:43 gott go. good night... sleep tight, don't let the bed bugs bite! Apr 01 03:32:51 Later for now. Apr 01 04:05:31 Hi, I'm using a BBB and trying to figure out how to go from successfully loading u-boot from the UART boot mode, to partitioning the onboard EMMC and making my /boot/ and rootfs persistant so that on the next boot I can boot straight from EMMC. Apr 01 04:05:58 abomination[m]: uart boot? o.O but why? Apr 01 04:06:11 of all the boot methods it supports, that sounds like the most awful one Apr 01 04:06:12 I won't have sdcard/usb access. Apr 01 04:06:29 ok so you mean a custom board, not a BBB Apr 01 04:06:38 yes Apr 01 04:06:47 no ethernet either? Apr 01 04:06:52 but PoC dev on BBB Apr 01 04:06:59 I will have ethernet Apr 01 04:07:10 So I can tftp things Apr 01 04:07:32 then netboot via ethernet sounds much more pleasant than trying to do it via the uart Apr 01 04:07:52 not going to lie the UART boot via XMODEM does suck Apr 01 04:08:04 (and it's something I've done successfully on the BBB, unlike xmodem boot) Apr 01 04:09:29 lemme see if I can find IRC logs of when I last talked to someone about this Apr 01 04:09:37 thank you Apr 01 04:16:01 abomination[m]: hmm, I found this bit but I know I've had a much more detailed conversation so I'll keep digging: https://pastebin.com/AmGTXXKg Apr 01 04:17:10 also, if you just want to first netboot *something* to see how that works, I also have a miniscule baremetal application that can boot directly (no u-boot), along with an example dnsmasq config file: https://github.com/mvduin/bbb-asm-demo Apr 01 04:21:22 abomination[m]: ok I've found the logs I was looking for, extracting the relevant bits now Apr 01 04:21:34 @zma Apr 01 04:21:45 zmatt: thanks Apr 01 04:28:51 abomination[m]: https://pastebin.com/NmpH1Xq8 Apr 01 04:39:26 abomination[m]: conversation about building the flasher rootfs: https://pastebin.com/aq0RBu2W Apr 01 04:42:05 that also includes a link to information about the tftp tree I used and how to build the FIT: https://pastebin.com/raw/YC5E6tw4 which combined with the dnsmasq config ( https://pastebin.com/raw/VLquWMfk ) given earlier and my u-boot netboot branch should be everything you need to get flashing over ethernet working Apr 01 04:42:57 and only missing ingredient is building an initramfs that performs the eMMC flashing Apr 01 04:54:38 wow ok, so basically get u-boot to use netboot/dnsmasq and then build a custom initramfs that partitions/flashes the emmc. Apr 01 04:55:35 thanks again for the detailed response. Apr 01 04:56:51 like I said in the logs: my netboot u-boot branch and a suitably setup tftp server the bbb would load u-boot SPL and u-boot proper via ethernet, and since I hadn't updated the boot script in u-boot I interrupted it via the serial console and manually typed "dhcp && bootm" to get it to load the FIT and boot the kernel Apr 01 04:57:39 so u-boot boot script would still need a small fix, and I mentioned the location for it near the end of https://pastebin.com/aq0RBu2W Apr 01 04:59:10 so just adding the dhcp && bootm to bootcmd in u-boot environment Apr 01 04:59:27 and you'll want an initramfs that does whatever it is you want the BBB to do, which is probably to somehow obtain an image over the network and write it to eMMC (and then probably expand the filesystem to fit the partition, randomize its filesystem uuid and machine id, set hostname, generate ssh keys, install bootloader) Apr 01 05:00:12 abomination[m]: I think you can just set CONFIG_BOOTCOMMAND to "dhcp && bootm" Apr 01 05:01:44 can you do partitioning from initramfs? Apr 01 05:03:07 why not? initramfs is as the name suggests just a filesystem in ram, which means that you can put anything you want into it as long as it doesn't take up an excessive amount of space Apr 01 05:03:25 (i.e. you probably don't want to put the image to-be-flashed into it :P ) Apr 01 05:03:31 lol Apr 01 05:04:55 ok, this is my first experience with real embedded linux dev so i'm tackling a bit of a learning curve Apr 01 05:05:14 like I said in the logs, it'll probably be busybox, a shell script that performs the task of flashing the system (which you could prototype by simply booting from sd card), and any supporting tools it needs Apr 01 05:05:24 (to the extent these aren't provided by busybox) Apr 01 05:05:56 you could probably also test your initramfs using systemd-nspawn Apr 01 05:07:32 systemd-nspawn seems neat: may be used to run a command **or OS **in a light-weight namespace container. In many ways it is similar to chroot(1), but more powerful since it fully virtualizes the file system hierarchy, as well as the process tree, the various IPC subsystems and the host and domain name. Apr 01 05:10:15 yeah it basically launches a container, except it has the benefit of also supporting partial containerization, e.g. you could make your prototype initramfs the rootfs of the container, but still allow it to have root privileges and the ability to see and modify the eMMC and either the real ethernet interface or a virtual one Apr 01 05:13:15 you can even use it to open a shell inside a beaglebone image on an x86 host machine, by install qemu-user-static and binfmt-support on the host machine and passing --bind-ro=/usr/bin/qemu-arm-static to systemd-nspawn to allow the arm executables in the container to be transparently emulated by qemu Apr 01 05:13:42 (this has some limitations, but it works surprisingly well) Apr 01 05:17:40 wow that's awesome Apr 01 05:19:50 yeah and you can even pass additional --bind-ro options to selectively "replace" individual executables by x86 versions when performance matters or the program does something that qemu doesn't know how to emulate (e.g. network admin tools) **** BEGIN LOGGING AT Wed Apr 01 06:45:14 2020 **** BEGIN LOGGING AT Wed Apr 01 06:48:05 2020 Apr 01 09:23:20 I am trying to make and use Beagle Board AI, but it is difficult to get parts. Where should I get it? Apr 01 09:24:23 you've checked all five of the distributors listed on the bbai webpage? Apr 01 09:25:19 all five say they have units in stock and can ship immediately Apr 01 09:26:12 though I don't know whether any of them are shipping right now due to covid-19 Apr 01 11:00:52 hi everyone!!! Apr 01 11:02:20 i have problems with bone_capemgr, can anyone help me? Apr 01 11:04:16 david_82: bone_capemgr is no longer in use on current images, it is deprecated Apr 01 11:05:04 overlays are handled by u-boot, though usually people just use the universal overlay (enabled by default) so you can configure pinmux at runtime Apr 01 11:06:09 where can i get information about that? a tutorial or anything else Apr 01 11:08:05 great question :P runtime pinmux can be configured using the "config-pin" utility, e.g. config-pin P9_11 uart Apr 01 11:08:23 presumably running config-pin without arguments (or maybe with --help ?) will get you some help information Apr 01 11:09:05 ok, but if you have to configure a spi driver Apr 01 11:09:30 you can just mux the pins to spi mode, the spidev device itself should already exist by default Apr 01 11:09:49 you need configure other parameters, would it be the same way? Apr 01 11:10:08 those are typically set at runtime via the spidev api Apr 01 11:10:29 if you want to set the defaults you'll still need to use an overlay Apr 01 11:11:48 (but in that case you may need to disable cape-universal to avoid conflicts, hence will lose the ability to use config-pin) Apr 01 11:12:35 this without tutorial it is very difficult Apr 01 11:12:52 yes I suggest you just set it at runtime instead Apr 01 11:13:15 (which is not beaglebone-specific, it works the same on all linux systems) Apr 01 11:13:49 runtime is a library of linux? Apr 01 11:14:22 i mean you can use for other devices different to beaglebone? Apr 01 11:14:39 ehh, it's a term that just literally means "at the time when running" (as opposed to doing some setup in advance) Apr 01 11:15:10 I mean that for spi you can just use any generic linux spi library for whatever programming language you're using Apr 01 11:15:27 c Apr 01 11:15:32 or c++ Apr 01 11:15:34 the only beaglebone-specific step you'd need to do is configure the pins, which you can do in one of three ways: Apr 01 11:16:47 (one moment) Apr 01 11:17:15 ok Apr 01 11:18:45 1. use config-pin: https://pastebin.com/4pbw3zek Apr 01 11:19:25 2. do the equivalent thing in software (i.e. set four sysfs attributes to the appropriate value) Apr 01 11:19:36 but if you want to configure the control register? Apr 01 11:20:45 3. enable one of the off-the-shelf spi overlays (e.g. /lib/firmware/BB-SPIDEV0-00A0.dtbo) in /boot/uEnv.txt, in either the dtb_overlay variable or one of uboot_overlay_addr4-7 (all five variables work equivalently) Apr 01 11:20:51 "the control register" ? Apr 01 11:22:04 in all cases the spidev device is /dev/spidev1.0 for spi 0 cs 0 ... the bus number is 1 higher than you'd expect for historical reasons. (if you have a sufficiently recent version of the "bb-customizations" package installed then there's also a symlink at /dev/spi/0.0 which uses the correct numbering) Apr 01 11:22:33 for example you want to configure the frequency Apr 01 11:22:56 like I said, that's part of the linux spidev API, so that works the same on beaglebones as it does on any other linux system Apr 01 11:23:36 (you can actually specify the clock frequency for each individual transfer, although you can also configure a default) Apr 01 11:24:38 ok, thanks for your help Apr 01 11:25:21 the low-level kernel API does so via ioctl()s, but there are probably libraries that provide a bit more abstraction... for example this python library simply lets you set the max_speed_hz and mode as properties: https://github.com/doceme/py-spidev#settings Apr 01 11:29:34 the low-level api isn't terribly complicated either in this case though: https://pastebin.com/wzWBnc81 Apr 01 21:10:29 GenTooMan: I think my testing of the LED was bunk. I just retested the same LED, the 12v automotive LED, w/ the same DMM. I received, during the continuity test, a low numerical value. Apr 01 21:11:11 To tell you the truth, I think I mislabeled the left and right side of the LED w/ the incorrect colors, i.e. red and black, respectively. Apr 01 21:11:20 Fixed Apr 01 21:19:58 things happen? did you check both directions to see if they behaved differently I presume? Apr 01 21:24:24 Yes. Apr 01 21:24:51 I thought since it worked on one end, that was the negative to use for the battery. I was mistaken on how to perform the test, I guess. Apr 01 21:25:13 Who knows? I got hashed out now. Apr 01 21:25:50 It is like it beeps on negative and positive w/ the DMM, though. What should I look for? A 0 or negative voltage/resistance? Apr 01 21:29:58 do you happened to have a diode handle like a 1n4148 or 1n4001? Apr 01 21:32:14 Diode Handle? What is a diode handle? Do you mean handy? I have one but i need to search for it. Apr 01 21:32:48 I do not know where it is exactly located right now. My organization skills have ceased recently. Please be patient. Apr 01 21:34:59 I have to run. UPS is calling. bbl. Apr 01 21:35:05 Sorry. Apr 01 21:37:34 handy don't mind me my brain sometimes gets in a fog and things come out in weird ways although sometimes quite humorously. Like Spooner was infamous for. Apr 01 21:40:26 Hey. Apr 01 21:40:28 on hand do you have a diode you can test you DMM behaviour based on the diode polarity. that's is all I was going to suggest Apr 01 21:40:30 UPS has been called off. Apr 01 21:40:39 Oh. Apr 01 21:40:41 Got you. Apr 01 21:40:46 I will get one shortly. Apr 01 21:40:50 UPS is no longer delivering? Apr 01 21:41:08 Not that. I had to make a trip to one of their locations but that is not longer happening. Apr 01 21:41:22 "too little, too late." Apr 01 21:41:26 ah Apr 01 21:44:26 I know I have one or more. Please stay w/ me on this one. Apr 01 21:46:29 I found two. Apr 01 21:46:31 Yea! Apr 01 21:47:04 can you tell the polarity of them? :D Apr 01 21:47:36 NO! It does have a gray line on one end of the actual diode, though. Apr 01 21:47:55 1N4001! Apr 01 21:47:58 Let me go and see. Apr 01 21:48:19 I purchased this from neward in 2015. Odd. Apr 01 21:48:27 that's probably the cathode. So see what it does when you test it with the DMM Apr 01 21:48:28 Newark = neward Apr 01 21:48:35 Okay. Apr 01 21:49:40 write down what it does based on the grey line being the cathode. with relation to the polarity of the wires from the DMM also make sure the positive lead is red and the negative lead is black. (it's different in the EU but oh well). Apr 01 21:51:15 okay. Apr 01 21:52:01 I got 0.52v with the gray end of the Diode as the cathode. Apr 01 21:52:32 50v, 1A diode... Apr 01 21:53:49 I tested it again. 0.518v. Apr 01 21:55:06 Should I reverse polarity to test to see what happens? Apr 01 21:55:47 GenTooMan: I am in the states w/ a US DMM. Apr 01 21:56:18 It was made in China but for the states. Apr 01 21:57:57 GenTooMan: If you want to build something or help out poor individuals during this "event," please look here: https://www.repurposedmaterialsinc.com/?utm_source=BenchmarkEmail&utm_campaign=Promo_sale_email_04-01-2020&utm_medium=email. Apr 01 21:58:03 Sorry for the long link. Apr 01 22:03:43 yes set reverse the polarity and remember what happense when you do Apr 01 22:03:54 Okay. I will write that down too. Apr 01 22:06:00 It gives an error code of 0.0L. The first way w/ the gray line as the cathode end must be correct. Apr 01 22:08:28 Okay. Something is up again. Apr 01 22:09:05 The LED gives the same voltage w/ the diode test w/ cathode/anode and if it is reversed too. Apr 01 22:09:20 repeat it to see if it works the same each time. Then test your LED bulb to see what it does. Apr 01 22:09:41 GenTooMan: Read one line above what you just typed. Apr 01 22:10:29 The diode test on the DMM, reversed or not, gives the same voltage on the LED terminals. Apr 01 22:11:19 I might have bought an irregular LED for testing. The inner workings will never be open source. I should reach out to another LED mfg. Apr 01 22:12:30 Does this behaviour match what it did before sparks? Apr 01 22:12:50 00.00v each time. Yes, the behavior does match what happened before the "issue" w/ sparks. Apr 01 22:13:23 I have three terminals that work and four other terminals on this LED that show error codes, e.g. just like always (before the sparks issue). Apr 01 22:13:39 Let me show you a close up of this LED. Apr 01 22:16:57 * GenTooMan tries his best confused look. Apr 01 22:19:03 Ha. Apr 01 22:19:25 Okay. The T's in this photo are just terminals. T = terminal! Apr 01 22:19:37 T on the LED are the metal terminals on it. Apr 01 22:20:13 https://drive.google.com/file/d/1sLtf26uwPyKYBz_ecZFvIZwBfKdL8-gG/view?usp=sharing Apr 01 22:20:46 I could not find the typing section, i.e. so the T's are drawn in. Apr 01 22:20:51 Oops. Apr 01 22:21:08 Sorry. Wrong photo. Apr 01 22:22:26 Anyway, you can see the terminals right? There are three on top and four on the bottom where my fingers are located. Apr 01 22:24:38 https://drive.google.com/file/d/1M2t49YBXSCZUh3y1B2FVz0vE1Ng6hP8l/view?usp=sharing <<< There. Apr 01 22:24:39 Sorry. Apr 01 22:26:05 set_: what kind of meter are you using? something modern with a LCD display or an analog vacumm tube meter? Apr 01 22:26:15 I got a spudger coming soon. I will get to the inner workings of this LED soon. Apr 01 22:26:22 DMM w/ LCD display. Apr 01 22:26:37 then use the ohm function Apr 01 22:26:42 It is a digital mutlimeter Apr 01 22:26:44 Ohm! Apr 01 22:26:45 Okay. Apr 01 22:27:01 as long as both ways don't ready a dead short... Apr 01 22:27:23 0.00 drop suggests it may be a dead short though Apr 01 22:27:41 Oh. Apr 01 22:27:51 Okay. Off to test the other one. Luckily, it was a double pack. Apr 01 22:28:19 I ripped one of the terminals out anyway. That probably shot it dead. Apr 01 22:28:31 Just now, trying to test it. Apr 01 22:28:41 what kind of LED? Apr 01 22:28:48 fancy $50 UVC ones? Apr 01 22:29:09 13 dollars! Apr 01 22:29:17 I will show you the link. Apr 01 22:29:27 THey are off-road LEDs for camping. Apr 01 22:32:00 https://www.amazon.com/SYLVANIA-3157-White-Contains-Bulbs/dp/B01BDWI1BS Apr 01 22:32:04 Those are them. Apr 01 22:32:30 Even w/ the untested LED, it still shows 000.0 as my reading for ohm tests, diode tests, voltage. Apr 01 22:33:50 I get a better reading on nothing compared to these LEDs. Apr 01 22:36:13 Continuity test works now on the untested LED! Apr 01 22:36:23 Beep, Beep! Apr 01 22:37:33 hmm that says one LED was toast huh? Apr 01 22:39:05 these may be trickier to test Apr 01 22:39:47 Yep. Apr 01 22:39:52 I think so. Apr 01 22:40:06 There are a bunch of terminals and none really read anything regular. Apr 01 22:40:28 There are four terminals on the bottom and three on top of this LED. Apr 01 22:40:58 The three top terminals read me out resistance and continuity at times. Apr 01 22:41:38 The bottom four terminals never have read anything useful. Apr 01 22:44:48 since it is for automotive, why not use a current limited power supply? Apr 01 22:46:14 Okay. Apr 01 22:46:47 Like...a fusez?Z Apr 01 22:46:53 Sorry. A fuse? Apr 01 22:48:02 Well, I will just wait. I think these alligator clips will prove useful when they arrive. Apr 01 22:48:17 This will help me debug this LED usefulness in the field. Apr 01 22:48:37 resistor Apr 01 22:49:49 Okay. Apr 01 22:50:26 So, where would I put this resistor on this LED or is that up to my debugging on this LED? I have a total of seven terminals. Yikes. Apr 01 22:50:59 I will figure it out. No worries. Apr 01 22:51:18 My DMM works. This is known. Thankfully. Apr 01 22:51:54 There was a fellow on the google groups saying that he might need the housing of this LED and wiring schematic of the housing to get involved. Apr 01 22:52:07 "Good luck to me? Apr 01 22:52:10 " Apr 01 22:56:54 Do not worry about it. I will try it out and try another LED is applicable during my testing. Apr 01 22:59:16 It's likely the terminals with long pins are the ones that are normally used. Apr 01 23:01:45 Okay. Apr 01 23:02:02 I will keep testing those in different configs. to see if a reading registers. Apr 01 23:02:02 IE those are normally plugged into sockets in the car :D Apr 01 23:02:08 Right. Apr 01 23:02:17 I understand. Apr 01 23:02:27 the resistor is to prevent excessive current flow by the way. Apr 01 23:02:36 This is why I figured things were a bit odd when they did not register on my DMM. Apr 01 23:02:38 Right. Apr 01 23:02:40 I got it. Apr 01 23:03:13 resist = current limiting Apr 01 23:03:15 Got it. Apr 01 23:03:36 Off to 'da sto'! bbl Apr 01 23:59:39 I think I just figured it out. Apr 02 00:00:06 The contacts only work when the contacts are applied pressure b/c they then connect in the encasing of the LED. Apr 02 00:00:07 Odd. Apr 02 00:04:07 they work as a switch\ Apr 02 00:05:44 Odd, heh? Apr 02 00:05:54 But... Apr 02 00:06:30 Once they are in their housings, they are just on until turned on. Apr 02 00:06:52 it is not like a bare LED showing leads/terminals. Apr 02 00:07:19 The leads/terminals need to have them securely pressured into working. Apr 02 00:08:04 Time to fashion something to apply pressure to the terminals. Apr 02 00:10:15 I don't understand ===> The contacts only work when the contacts are applied pressure b/c they then connect in the encasing of the LED.:O Apr 02 00:11:04 Do you hear the relays click? Apr 02 00:11:56 Yea. This LED has a housing that it fits into. The contacts, when applied pressure (supposedly in the housing), attach or touch the interior parts to the LED mechanisms. Apr 02 00:12:03 My relay board should be in Friday(y) Apr 02 00:12:09 Nice. Apr 02 00:13:16 You have an led - resistor to relay contacts and power?(y) Apr 02 00:14:00 Trying over here. The dang LED is giving this brother complications. Apr 02 00:14:47 just hook it to power directly. Does it light? =$ Apr 02 00:15:10 GennooMan Good evening Apr 02 00:15:13 No! Apr 02 00:15:19 It sparks. Apr 02 00:15:36 This spudger should do the trick once it comes in. Apr 02 00:15:41 sparks? how many volts are you giving it? Apr 02 00:16:04 12v Apr 02 00:16:04 Spark? What exactly do you have ?X) Apr 02 00:16:14 12v LED at 2A Apr 02 00:17:09 Wait, most leds are for 5 volts with a series resistor =# =# Apr 02 00:17:27 KenUnix: look at the link... this is an automotive thing Apr 02 00:17:38 12v and 2A! Apr 02 00:18:12 OK then it's built in Apr 02 00:18:15 The undebuggable LED. Blah. Apr 02 00:18:21 Right. Apr 02 00:18:33 Well, my theory did not work. Apr 02 00:18:47 I pushed the contacts in like a housing would do and nothing still. Apr 02 00:19:17 Check polarity Apr 02 00:19:58 ds2 , I missed link... Apr 02 00:20:06 I guess all four contact need to be in one test to find out if it works. <<< My next theory. Apr 02 00:20:45 do you have an ohm meter Apr 02 00:21:01 Yes. Apr 02 00:21:09 I have tested it completely. 000.0. Apr 02 00:21:17 or an error code. Apr 02 00:21:28 what do you read across bulb contacts Apr 02 00:22:04 Hey. KenUnix: Sorry, let me update you. Apr 02 00:22:36 The LED in question has been tested at 000.0 w/ ohms, diode, and continuity. Apr 02 00:22:44 I tested volts, too. Apr 02 00:23:07 The free world is waiting for your bulb to light ;( ;( Apr 02 00:23:15 I even decided to check the rest of the functions on this DMM, i.e. Hz and mA. Apr 02 00:23:24 Let me get you the photo. Apr 02 00:24:09 https://drive.google.com/file/d/1M2t49YBXSCZUh3y1B2FVz0vE1Ng6hP8l/view?usp=sharing <<< All the T's I drew in are terminals that read nothing. Apr 02 00:27:32 I got the continuity test to work. The top contact on the LED works w/ one of the top-side contacts. Apr 02 00:28:49 Somehow the 0.02 ohms. Apr 02 00:28:51 Too many T's. Don't you have a regular bulb? Set the DMM to ohms touch relay C and NO. Should read open. operate relay should show 0 Apr 02 00:29:12 No regular bulb. How much fun is that? Apr 02 00:29:55 So, somehow the top is positive and the top-side is negative. I read continuity and 0.02 ohms. Apr 02 00:30:01 Test. Set the DMM to ohms touch relay C and NO. Should read open. operate relay should show 0:] :] Apr 02 00:30:29 Okay. Apr 02 00:31:19 KenUnix: I am testing this bulb, the automotive LED, just w/ the DMM for now. Apr 02 00:31:23 probably a better test although watching a light is cooler Apr 02 00:31:36 I am waiting for some alligator clips to show up. Apr 02 00:31:41 Right! Apr 02 00:31:44 Just you wait. Apr 02 00:31:57 I will blind the opposums in the back yard! Apr 02 00:32:24 I am trying to establish if the relay is working OK;D ;D Apr 02 00:32:32 Oh ... I have a CREE luminary rated at 40W so I can light toilet paper on fire with it. Apr 02 00:32:49 Ha. Apr 02 00:33:02 Yes. The relays on the Cape work fine. Apr 02 00:33:03 not joking I have done it already. Should show a video. Apr 02 00:33:09 No. Apr 02 00:33:11 Please do not. Apr 02 00:33:17 Ha. Apr 02 00:33:29 Between here and there I am loading Zorin-15.2 Linux Lite Apr 02 00:34:10 Yeah the smoke detector will go off. have to do it outside. Though I'm sure the neighbours will see this searing bright light and report a UFO or something. Apr 02 00:34:31 Procedurally, KenUnix, what are we going to do w/ these RelayCapes? Apr 02 00:34:32 Ha. Apr 02 00:34:44 "I swore someone probed something!" Apr 02 00:34:53 Lights, cameras, lies!" Apr 02 00:35:21 I suggest using them to control a contactor to switch power on off in a building. Apr 02 00:35:28 I'll better know Friday. Oooh UFO 8) 8) Bright light Apr 02 00:35:43 Probes are funnier. Sheesh. Apr 02 00:36:18 I say 2 x 4 locks on the doors. This way, when the people come knocking, we can yell at them from safety. Apr 02 00:36:34 Like in Startrek probes?X-P X-P Apr 02 00:36:48 Right or some other adaptation probing. Apr 02 00:37:25 Bzzt, bzzt. KenUnix: Hey man, can we please make some solenoid locks that will deter things/people from entering? Apr 02 00:37:36 "Do not enter!" Apr 02 00:38:06 Like Trump and his wall, we could make a makeshift door lock of many uses w/ one solenoid! Apr 02 00:38:20 It pulls in and then releases! Apr 02 00:39:19 I have 3 of these https://www.cree.com/led-components/products/xlamp-leds-integrated-arrays/xlamp-cmt1945 Apr 02 00:40:27 Parking lights must be heavy on the eyes. Apr 02 00:40:34 34.x volts! Apr 02 00:40:44 1.2A 34V Apr 02 00:40:46 One LED, yikes! Apr 02 00:41:19 I remember someone selling something a while back. It was a simple LED turned into a light beam strong enough to burn things. Apr 02 00:41:21 They have single LED emitters rated at 120W this is a multichip array. Apr 02 00:41:34 Wozzers. Apr 02 00:41:36 nothing like 20A into an LED Apr 02 00:41:40 Ha. Apr 02 00:41:58 I did say I wasn't kidding. Apr 02 00:42:03 Light sticks! I think that is what the military uses to blind people w/out killing them. Apr 02 00:42:04 Oh. Apr 02 00:44:02 I get the best animals in my backyard in this city. Would you like to know why? Apr 02 00:44:35 Fine, I will tell you. Apr 02 00:44:45 No one ever answers my odd questions anymore. Apr 02 00:45:26 I turn on bright lights. This attracts bugs. Bugs attract spiders. Spiders attract birds. Apr 02 00:45:44 Birds attract more bugs b/c of their, well you know. Apr 02 00:46:08 And then, the rest of the marsupials and other animals devour the bugs too! Apr 02 00:46:20 It is a cycle. Apr 02 00:48:00 I remember one year in NYS their was this insane cricket explosion. Entire yards had a cloud of crickets hopping through them. A few days latter troops of wild turkeys literally mowed through yards all over the place. Their was a sharp rise in the turkey population as a consequence. Apr 02 00:50:22 Nice. Apr 02 00:50:50 The dang owner keeps telling me to put down bug poison and fertilize. I try to act like I am sick or something. Apr 02 00:50:59 ha. Apr 02 00:51:19 Bugs are so neat. I have a bucket full of them right now w/ a spider friend eating them. Apr 02 00:51:33 The spider grew an inch overnight. Apr 02 00:52:07 I feel bad, though. I should have recorded the spider eating all those bugs w/ my BBB. Apr 02 00:52:19 I could have proof and study it. Apr 02 00:52:32 no gators? Apr 02 00:52:42 Down the road. yea. here, no. Apr 02 00:52:54 Moccasins! Apr 02 00:52:57 GenTooMan: thanksgiving must be nice that year Apr 02 00:53:04 We get little ones when the rains are not forgiving. Apr 02 00:53:07 Water Moccasins? Apr 02 00:53:10 Yea. Apr 02 00:53:16 Copperheads! Apr 02 00:53:28 is waders enough to deal with their bites? Apr 02 00:53:34 I am in the city, too. Apr 02 00:53:35 No. Apr 02 00:53:47 It depends I guess. Apr 02 00:54:06 double waders? Apr 02 00:54:07 Thick, snake proof waders. yes. Regular, no. Apr 02 00:54:34 I had a couple of snakes try to get my old cat. I had to chase them away w/ sticks. Apr 02 00:54:57 get a mongoose? Apr 02 00:55:20 I wonder how well would a webcam plus BBAI work for spotting snakes Apr 02 00:55:31 ds2: I came outside once to get my cat before bed (no mongoose) once. The cat was sleeping near three snakes. Apr 02 00:55:33 It was weird. Apr 02 00:55:36 This is just like National Geographic \O/ \O/ Apr 02 00:56:00 Right-o! Geogpraphic stuff can be put into electrical ideas too! Apr 02 00:56:21 From videography to tracking. Apr 02 00:56:32 I used to watch that on Apr 02 00:56:34 PBS Apr 02 00:56:52 I mean, look at what the TU Delft college put together. Apr 02 00:57:02 They have this neat boat w/ the BBB attached. Apr 02 00:57:08 Solar! Apr 02 00:58:37 Reboot. Installing Vbox addons Apr 02 00:58:57 Talk about some odd bugs and different types of animals. Apr 02 00:59:14 Skirting the seas in their rift might be worth it. Apr 02 00:59:38 Let me show you all the link. Apr 02 00:59:50 Take plenty of fresh water Apr 02 01:00:29 https://beagleboard.org/blog/2020-03-26-beaglebone-black-solar-boat-team Apr 02 01:00:44 That is as recent as possible w/ their boat ideas. Apr 02 01:00:48 That is super neat. Apr 02 01:01:35 I have a 2A 5v power adapter w/ working solar panel! BBB? Apr 02 01:02:35 It is very much possible to just plug and play w/ that thing w/ my BBB. Apr 02 01:03:22 I hope their WiFi works better then mine Apr 02 01:03:49 Who? TU Delft? Apr 02 01:04:06 I first heard of them from coursera years ago. Apr 02 01:04:17 They were teaching grids and solar stuff. Apr 02 01:04:20 For free! Apr 02 01:05:31 Yea. Mine goes up and down 4-5 times a day. At least it auto recovers now Apr 02 01:06:11 Hmm. I used to have issues. Unplug and replug every couple of weeks! The newer and older modems get hot and cause issues to itself. Apr 02 01:06:29 one of the biggest issues with a freighter is loosing power. With solar panels aboard even in bad weather it's possible for them to keep limping forward when they have engine issues. Apr 02 01:09:59 http://emag.nauticexpo.com/hydrofoils-main-pros-and-cons/ is what you are conveing? Apr 02 01:10:07 Hydrofoil? Apr 02 01:11:13 Like pontoon! Apr 02 01:11:19 Same idea sort of. Apr 02 01:14:02 It is like the car spoiler of the sea! Apr 02 01:15:38 just get a fan boat Apr 02 01:16:05 This is what I've been working on https://pastebin.com/h4tJaZ0T Apr 02 01:18:15 ds2: Right-o. If I could get one and had the guts to go back out to the swamps, I would. Apr 02 01:18:55 thought everyone has one there? Apr 02 01:19:05 Too many odd fish and gators. I cannot even swim in the waters out in the swamps. It is not smart to swim w/ gators. Just saying. Apr 02 01:19:08 I wish. Apr 02 01:19:15 I would go fan boating constantly. Apr 02 01:19:25 <<< low guts, low glory Apr 02 01:20:31 Popular opinion >>> keep low guts and low glory is my idea b/c I am popular to me! Apr 02 01:23:52 kenunix if you need ssh for sftp filezilla is a great option (FYI) Apr 02 01:29:35 https://lockeyusa.com/panic-hardware is what I was discussing. Apr 02 01:29:49 A master lock of deadbolts. Apr 02 01:29:53 W/ eletronics! Apr 02 01:31:44 Scratch that link. Sorry. Apr 02 01:31:53 That is not what I was describing earlier. Apr 02 01:32:11 neccesary hardware for CA huh? Apr 02 01:33:35 Ha. Apr 02 01:34:05 I was thinking that w/ mechanics and electronics, a slide of hefty door jammers would be nice. Apr 02 01:34:11 GenTooMan - I'm using winscp Apr 02 01:34:40 GenTooMan - I'm using winscp Apr 02 01:34:46 GenTooMan - I'm using winscp Apr 02 01:35:06 GenTooMan - I'm using winscp (y) (y) Apr 02 01:35:25 I see I see I see I see e e Apr 02 01:35:48 GenTooMan , I am using winscp Apr 02 01:36:33 Got confused scroll went off screen Apr 02 01:40:22 https://www.dormakaba.com/us-en/solutions/products/electronic-access---data <<< dudes, look at this! Apr 02 01:40:23 Neat. Apr 02 01:40:35 Not what I am desiring but I will keep looking. Apr 02 01:40:46 Then, off to make it! Apr 02 01:41:21 well now actually I was reading this https://www.electronicsweekly.com/blogs/engineer-in-wonderland/current-sink-stability-2015-10/ Apr 02 01:45:40 Was that a door lock w/ electrical connection for warnings? Apr 02 01:46:57 OhOh Door & Elevator Floor Controllers Apr 02 01:47:10 Yea boy! Apr 02 01:47:49 no it was a circuit for making a constant current sink stable (IE LED driver) type thing. Otis any one? A friends father use to be an Otis elevator installer went up in a new building under construction to view the Gulf of Mexico. Apr 02 01:48:03 Oh like Drano. Current sink stability Apr 02 01:48:45 indeed your LED will never get over burdened with current flow (IE see resistors are a bad idea for that application). Apr 02 01:48:57 Westinghouse used to make good evevators Apr 02 01:49:30 westinghouse use to make a lot of things. Then George got the boot and the idiots took over and killed the company. Apr 02 01:49:59 Oh. Apr 02 01:50:51 by they way they really were idiots. A guy ordered a yacht with the companies money and forgot to tell them where to deliver it. Apparently it got delivered to the division he was a part of. Apr 02 01:50:56 How about that! It's like Hewlett Packard fuc..ed servers. That bitch from the west screwed thing up Apr 02 01:51:26 GenTooMan and KenUnix: Can you fellows tell me what it is called when something slides across the door, entry door, to lock it w/ stability and security? Apr 02 01:51:46 bolt? door slide? Apr 02 01:51:51 I have been searching and trying to make it w/ the RelayCape but I keep getting door sellers instead of the actual locking mechanism. Apr 02 01:51:54 I will try again. Apr 02 01:52:09 I tried those already. Apr 02 01:52:10 Slide , gateway Apr 02 01:52:15 I tried. Apr 02 01:52:20 banana? Apr 02 01:52:42 Slip & slide banana Apr 02 01:52:50 Fine. I will check banana. Apr 02 01:52:51 Gosh. Apr 02 01:52:55 :D Apr 02 01:53:07 Do you two understand what I am decribing? Apr 02 01:53:23 Got no clue Apr 02 01:53:39 it is like a long latch for the door that slides from left to right or vice versa to counter a forced entry. Apr 02 01:55:10 grainger has them. Apr 02 01:55:12 I found 'em. Apr 02 01:55:22 Outdoor bolt latch. Apr 02 01:55:32 I would show the link but it is too long. Apr 02 01:55:37 Three or four lines. Apr 02 01:56:05 Now, to make it electronical w/ the relayCape and have realtime accessorizing due to the BBB. Apr 02 01:56:12 Linux! Apr 02 01:56:41 cp -r /linux/current/* . Apr 02 01:56:56 THey are trying to charge $120.00 for a metal latch. Silly! Apr 02 01:57:29 Do they mean sanding some iron ore, coating it, and then polishing it. The BBB obviously comes in later! Apr 02 01:58:24 https://www.grainger.com/product/ROCKWOOD-Heavy-Duty-Surface-Bolt-3HJE2 is it more or less. Apr 02 01:58:44 I can make my own, then add the electronics, and realtime! Apr 02 01:58:45 BBB! Apr 02 01:58:57 KenUnix: are you in? Apr 02 02:00:54 solenoid, surface bolt, and the BBB! Apr 02 02:01:35 We can make a couple of fancy UX interfaces and put the final touch on it. Apr 02 02:02:06 Then, we can record it somehow (you know...to put it in the books). Apr 02 02:02:53 Yes back trying to get ssh to connect to new vn Apr 02 02:04:02 set_ But you can't get an LED to light X) X) Apr 02 02:05:27 set_ what are you making a fall out shelter? 8) :b Apr 02 02:05:45 wapeul: don't send unsolicited private messages Apr 02 02:06:08 wapeul ?? Apr 02 02:06:47 Ha. Apr 02 02:07:12 https://github.com/beagleboard/beaglebone-ai/blob/master/BeagleBone-AI_bom.csv Apr 02 02:07:23 No, just some nice, sturdy (eletromechanical) doors w/ access to the Internet. Apr 02 02:07:31 zmattt I sent him a message to leave you alone. Apr 02 02:07:33 Or private servers... Apr 02 02:07:34 I want to make a board. Apr 02 02:07:38 Sorry Apr 02 02:07:42 KenUnix: what? Apr 02 02:08:22 It's OK Apr 02 02:08:29 Wink, wink. Apr 02 02:08:32 Ha. Apr 02 02:08:43 KenUnix: no? Apr 02 02:08:52 why Apr 02 02:10:12 KenUnix: I'm honestly lost at your train of thought here... I told someone to not send unsolicited private messages, and that gave you the random urge to send them a private message on my behalf? Apr 02 02:10:40 KenUnix: This LED is a trick LED. It is like the B-Day candle that cannot be blown out. Apr 02 02:11:27 Except in this case, the LED does not register on a DMM. Apr 02 02:11:36 And then it does! Apr 02 02:11:38 Aw. Apr 02 02:12:10 zmatt - Funny ideas in my old age Apr 02 02:12:43 I can't get ssh to login into new Linix VM Apr 02 02:12:58 I opened port 22 Apr 02 02:13:09 wapeul: I'm sorry but if you have to ask a question like "Can you tell me where to get the parts?" I very sincerely doubt you have the resources and expertise to make any board, let alone one as complicated as the bbai Apr 02 02:14:06 what is your goal/motivation here? Apr 02 02:14:18 I don't undrstand other VM's work with port 22 open Apr 02 02:14:41 KenUnix: Fine, forget it. I will do it myself. Apr 02 02:14:46 KenUnix: I mean, if the VM has its own IP address then it can open whatever ports it wants Apr 02 02:15:44 (and generally a VM will have its own IP address, sharing the host network stack is generally only a thing for lightweight containers, not full VMs) Apr 02 02:17:27 Well the connection opens them gets closed by the VM Apr 02 02:18:03 what's the actual error message from ssh? Apr 02 02:18:16 Most parts were found to be purchased or replaced. Apr 02 02:18:29 Let me stop this VM and fireup one that worked to see what happens Apr 02 02:19:30 Fire wall rule is : 22 ALLOW Anywhere Apr 02 02:19:56 I mean, if it worked with one VM but not the other then presumably it's just some sort of issue with the non-working VM Apr 02 02:20:07 none of this is what I asked though, I asked for what error you got exactly Apr 02 02:22:19 Linix Mint came up fine. Soo it's something to do with Zorin-15.3 Linix Apr 02 02:22:40 Linix Mint came up fine. Soo it's something to do with Zorin-15.2 Linux Apr 02 02:23:04 Let me try Zorin again..... Apr 02 02:23:34 did you install openssh-server on zorin? Apr 02 02:24:41 Wait//// Apr 02 02:27:50 yes - sudo apt-get install openssh-client openssh-server Apr 02 02:29:46 Connecting to 127.0.0.1:2222...Connection established.To escape to local shell, press 'Ctrl+Alt+]'.Connection closing...Socket close.Connection closed by foreign host. Apr 02 02:31:44 why 127.0.0.1 port 2222 ? what is that? Apr 02 02:33:41 trojan? Apr 02 02:34:12 KenUnix: I would expect you'd simply connect to port 22 of your VM Apr 02 02:35:51 getting a spontaneous disconnect makes sense if you're trying to connect with ssh to something that isn't ssh, e.g. using openssh client to try to connect to port 80 of a webserver yields "kex_exchange_identification: Connection closed by remote host" Apr 02 02:36:59 I can't tell from your ssh client's output at what point it actually got disconnected Apr 02 02:39:51 OK port 127.0.0.1 is VM host port 2222 is forwarded to port 22 at 10.0.2.15 Apr 02 02:40:08 forwarded? from what and why? Apr 02 02:40:17 It works now. I reinstalled it. Apr 02 02:40:35 just connect to port 10.0.2.15 port 22 ? Apr 02 02:41:14 let me try that hold Apr 02 02:42:49 no good. 10.0.2.15 is an well known address used by VM guest Apr 02 02:43:02 ?? Apr 02 02:43:38 oh you have some weird virtual networking setup that completely isolates the VMs? why? Apr 02 02:43:58 Virtual Box does that Apr 02 02:44:07 sounds obnoxious Apr 02 02:44:38 Took me awhile to find that on the web. But, it works Apr 02 02:50:10 OK IP assigned to VM guest is 10.0..2.15 Apr 02 02:53:19 zmatt take a look at : https://bobcares.com/blog/virtualbox-ssh-nat/ Apr 02 02:54:11 yes I understood that you were using NAT, I just personally wouldn't Apr 02 02:54:27 that article already begins wrong, it seems to confuse NAT with port mapping Apr 02 02:54:53 NAT isn't what's allowing SSH access, it's what's *preventing* access, and port mapping is the workaround Apr 02 02:55:01 But there is a table mapping ports Apr 02 02:55:33 Setup appears under network and nat on VM host Apr 02 02:56:33 yes, port mapping (aka port forwarding) is generally only used when NAT is being used, which is why you find it there Apr 02 02:56:47 I don't think I want to fight an up hill battle Apr 02 02:57:00 I'd just want the VM on my network like any other host Apr 02 02:57:16 oh maybe you can't if you're using wifi Apr 02 02:57:39 That would be nerwork sharing then? Apr 02 02:57:48 network sharing uses NAT Apr 02 02:58:17 I was thinking of bridging (or macvlan, but that's linux specific) Apr 02 02:59:24 The only other choice I have is "bridged network". The last time I tried that my PC WiFi went down. Apr 02 02:59:34 but you can't bridge to a wifi connection (although windows lets you do it and it has somehow worked for me in the past... I wonder if they secretly do ARP proxy or something like that) **** ENDING LOGGING AT Thu Apr 02 02:59:57 2020
